T 0 (ZZZ/107mm it may concern Be it known that I, lllARIU-S MnrHiLrUs SonnNsnN, a subject of the King of Denmark, residing at Vallerod, near llungsted, Isle of Sealand, in the Kingdom of Denmark, have inventedcertain new and useful Improvements in Lasting Machines, of which the following is a specification.

This invention to improvements in machines for lasting foot-wear, with lasting threads or wires instead of nails. The object of the invention is to provide improved mechanism for tensioning the lasting threads or wires. i

l Vith the foregoing object outlined and with other objects in view which will appear as the description proceeds, tie in ention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing and. more particularly pointed out in the appended claims.

, Referring to the drawings Figure l is a vertical longitudinal sectional view of my improved machine.

2 is a top plan view of the same.

Fig. 3 is a transverse vertical sectional view of the machine.

Fig. 4 is an enlarged side view partly in section of the upper portion of the machine.

In the drawing. 1 designates a box-like frame, one side of which, has a liiearing for a driving shaft 5, which is carried by Slll r able bearings within the frame and projects outwardly at one end of the machine as shown. A shaft 6 arranged at right angles to the shaft 5, has its ends journaled in opposite sides of the casing 4e, and ahollow stem 8 is journaled in the top plate 7 of the frame and has a portion extending up wardly above said plate. A hand. wheel. shaft 10 and an obliquely arranged sliding rod 9 also extend through the top plateof the frame. The driving shaft 5 is mounted. for axial movement and manually controlled. means are provided for shifting the shaft axially. This latter means includes a lever 11 having itsinner end fixed to a vertical rock shaft 11* and having its outer portion extending through aslot in the front side of the machine frame andcarrying a knee engaging member 12; An arm 11 is fixed to the rock-shaft 11 and is provided at its outer end with a fork-shaped member which engages an annular groove provided in the end l1 of the shaft 5. From this construc- Spccification of letters Patent.

tion. it will be readily understood thats hiftmg of the member 12 in opposite directions will cause corresponding shifting movements of the shaft 5 in opposite directions. i

The shaft 5 is provided at its outer portion with a fixed pulley 13 and two loose pulleys l4 and 15. the latter pulleys being rotated in opposite directions by anysuitable means (not shown). The pulley 13 moves axially with the shaft 5 while the pulleys 14 and 15 do not move axially.

Part of the driving shaft is provided with a screw-thread 5O engaged by a non-rotatable nut 51 which, by the rotation of the driving-shaft, is caused to move along a rail 52 until it strikes against one or the other of two stops 53 and 5 2. On arriving at either one of the stops, itwill compel the driving-shaft to move longitudinally, sothat the friction-pulley 13 is automatically frelcased from the driving-pulley 14 or 15 respectively, and the rotation of the: driving shaft automatically ceases.

A worm 1.6 is mounted on the shaft 5 in such manner that the worm will turn with the shaft and the shaft can move axially relative to the worm. The worm l6 meshes with. an axially ijinm'ovably journalerlworm 17 which is internally threaded at 17 to engage a screw-stem 18. This stem is adepcnding extension of the ate/m8 and has a head lil which. abuts a: shoulder 20 arranged at the lower end of the upper or main portion of the stem 8.

support a heavy weightQl. The upper end This shoulder serves to oftho stem 8 has a head 29. provided on its underside with an animlar groove having a conical surface, and this groove is designed to receive a conical sleeve 23 which 1S carried by a hand wheel 24:, arranged to. turn on a screw-thread 25 on the stem 8. In the head 22 there is a recess 26, through which the ends of the lasting-thread 27 for the front part 28 of the foot-gear can be passed in between the conical surfaces on theaforesaid members 22 and 23.

The hollow stems 8 and 1 8 enclose a spindle 29, which is connected with the hand wheel shaft 10 by two pairs of bevel wheels 30 and 31 at the bottom of the frame..A bracket 32, mounted on the table 7, is pro:

vided with a bearing for the upper part- I of the spindle 29, which has a hole corresponding to the rod which actuates the clamping device 33 for holding aforesaid lasting-thread 27. The clamping device 33 Cir may be of any suitable construction but it is preferably of the type shown in my Patent 1224229. As will be seen by Fig. 1, the spindle 29 serves to support the rear part of the last.

Besides the member 12 to be actuated by the knee, there is also at the front of the frame, a pedal 34 carried by a lever 35 which is pivotally mounted on a bracket 35' and has its rear end connected to a weight 36. This is by means of an arm 3'7, suspended on the shaft 6, which, by means of another arm 38, isconnected with the oblique rod 9, which ends with a clamping device 39 for fastening the ends of the lasting thread 40 to the counter 41.

At a suitable distance from the bracket 32, on the plate 7, is arranged a supporting member 42, which can be turned out to one side and can be adjusted in height.

In using the machine, the last, with the leather pulled over it, is disposed in the manner shown in Fig. 1. When the member 12 is moved to one side, the driving-shaft is caused to rotate in the direction which causes the lower stem 18 to rise. The upper stem 8 with the weight 21. and the thread clamping device 22, will then also. be lifted. When the rotation of the drivingshatt and the upward motion of the stem is automatically stopped, in the aforesaid manner, by the action of the members 50 and 54, the lasting-thread 27 is introduced into the recesses 26 and clamped fast by the turning of the hand-wheel 24. Then the member 12 is moved over to the other side, then the stem 18, which has hitherto sup ported the weight 21, is screwed down, so that the weight hangs on the thread 27 and causes the tensioning ot the thread. All this time the toe of the last rests. as shown, on the support 42, and with but a few blows from a suitable tool, the hammering of the edge of the upper or the so callel pounding-np is done. which work. owing so the absence of nails, is simple and brief and does not require any further steps to be taken. The rotation 01 the driving shaft and the downward motion of the stem 18 stops automatically in the atoresaidinanner; and. after the poundin irs-up operation the hand-wheel shaft 10, and therewith the shat't are turned, whereby the clamping device is put into action and loclcsthelasting thread in stretched condition, so that it can now be released from the clamping device 22, 23, without being slackened. Then the support 42 is thrown to one side. and the oblique rod 9 is pushed out a certain distance by pressure on the pedal 34. T he lasting-thread 40 is made fast in the clamp 39, and, when the pedal is released, the weight 36 exercises a pull on the lasting-thread,

whereby the counter is also lasted and is then pounded up with a few strokes, the same as described with respect to the front part. A small apertured conical body 43 is then passed in on to the thread 40 close to the upper, and a pin 44 is inserted into its hole. so that the thread is maintained in stretched condition and can now be released from the clamp 39 without being slackened.

In order to insure an even fall of the weight 21 and to prevent breakage of the machine, in case the thread 27 should break while the weight is hanging on it, the weight may be coupled to a suitable brake 45 by means of a fork-lever 46, or the like.

On the whole the shown details are, not essential for the invention, and they can be modified in many different ways.

I claim:

1. A lasting-machine for lasting with tension thread, including a lower stem, an upper stem, a load for the upper stem, a thread-clamp on the latter stem, and means for moving the lower stem up to lift the upper stem against the load, to permit the thread to be secured to the clamp in an elevat'ed position and for moving the lower stein down so that the load will become etlective to stretch the thread.

A lasting-machine for lasting with tension thread, including a lower hollow stem, an upper hollow stem in prolongation of the lower stem, an axially unmovable spindle inside these stems, a load for the upper stem, a thread clamp on the lastmentioned stem, another thread-clamp on the said spindle, means for moving the lower stem down, thereby making the load effective, and means for turning the spindle and thereby making the thread-clamp thereon effective,

3. ft lasting-machine for lasting with tension thread, including means for securing the lasting thread of the front part; means for moving the secured thread ends in the direction of the tension; means for securing the lasting-thread of the counter, said means being disposed on a guided rod; a load for this rod; and means for moving the rod against the load in a direction towards the last.

In testimony whereof I athx my signature in the presence of two witnesses.
